An agronomist is studying fertilization for potato farming. He compares the number of tones of potatoes produced per hectare (the yield) over several parcels of land. Different levels of phosphorus fertilizer are applied to each parcel of land. The results from his experiments are represented in the following scatter plot: The agronomist determined that the equation of a regression line that passes through points (0, 23) and (190, 37) corresponds to y = 0.07x + 23. If the agronomist wants to produce approximately 60 tonnes of potatoes per hectare, what quantity of phosphorus fertilizer (kg/ha) should he use. Describe the reliability of your answer with mathematical arguments.
